Per Ray Baughman & Dwight Cook, I've tried moving the data (several times),
but...

     ANR2017I Administrator TBYRNE issued command: MOVE DATA d00082
     ANR2209W Volume D00082 contains no data.
     ANR2017I Administrator TBYRNE issued command: ROLLBACK
     ANR2017I Administrator TBYRNE issued command: DELETE VOLUME d00082
discardd=yes

     ANR2017I Administrator TBYRNE issued command: DELETE VOLUME d00082
discardd=yes

     ANR2406E DELETE VOLUME: Volume D00082 still contains data.

I then tried changing the access to READOnly per Jim Sporer's suggestion; that
seemed to have no effect, even after re-running the delete volume command.

I also tried Francisco Molero's suggestion to run an AUDIT VOLUME.  However,
this requires physical access to the volume, so I'm having it returned by the
courier.  Hopefully that will clean up whatever condition is preventing the
volume from going empty.  At the very least, hopefully it will clarify what the
problem is...
